基于模型的故障诊断在飞机电源系统中的应用

传统故障诊断方法越来越难以应付更加复杂和智能化的现代飞机电源系统,基于模型诊断方法是为了克服传统诊断方法的缺点而兴起的一项新型的智能故障诊断技术。运用基于模型的故障诊断原理,建立飞机电源系统的定性仿真模型,对飞机电源系统负载故障进行模拟故障诊断,分析电源系统关键部件的故障对关键负载的影响,验证飞机电源系统的可靠性。

Application of Model-Based Fault Diagnosis in Aircraft Electric Power System

Traditional fault diagnosis methods were increasingly difficult to cope with complex and intelligent modern aircraft electric power system. Model-based diagnosis method, a kind of new and intelligent fault diagnosis technology, was designed to overcome the shortcomings of traditional diagnosis methods. By use principles of model-based fault diagnosis, we established a qualitative simulation model of aircraft electric power system, simulated fault diagnosis of aircraft electric power system load failures,and analyzed the effect of key components faults on critical load, verified the aircraft power system reliability.
